first embodiment

[0029]A first embodiment describes control of processing in an image processing apparatus by which settings of an amount of toner saved are controlled and an image quality that a user desires can be ensured.

[Description of the Outline of the General Configuration]

[0030]FIG. 1 is a schematic view showing a configuration of a system having an image processing apparatus 101, a host computer 102, and a host computer 103 for achieving toner saving.

[0031]The image processing apparatus 101 can provide printouts from the host computer 102 and the host computer 103 that receive instructions via a network 104. Further, the image processing apparatus 101 can send image data read by utilizing an image reading apparatus provided with the image processing apparatus 101 to the host computer 102 and the host computer 103. Still further, the image processing apparatus 101 can print the read image data (copy operation) by utilizing a printer provided with the image processing apparatus 101.

[0032]In t...

second embodiment

[0064]In addition to the method for achieving a target amount of toner saved as the first embodiment, in a case where a target amount of toner saved is set for each object, it is desirable to achieve the target amount of toner saved for the same object type as the excluded object.

[Process of Instructions for Toner Save Printing]

[0065]FIG. 10 shows an exemplary screen displayed on monitors of the host computers 102 and 103 or the UI unit 206 of the image processing apparatus 101.

[0066]Every time a user wants to print data, the user sets an amount of toner used in toner saving on a pull-down menu 1001 and enters it by pressing a button 1002. This can be canceled by pressing a button 1003. On the pull-down menu 1001, an amount of toner used in toner saving appears for each image portion and character portion.

[0067]FIG. 11 shows exemplary printouts of print data 301 from the image processing apparatus 101 in a case where, for example, reduction rates of 75% and 50% are set for the image...

third embodiment

[0076]In addition to the process described in the first embodiment, it is preferable that there are many processes for selecting an excluded object. In this embodiment, a process for selecting an excluded object that is different from the one described in the first embodiment will be described.

[0077]FIGS. 13 and 14 show an exemplary screen displayed on monitors of the host computers 102 and 103 or the UI unit 206 of the image processing apparatus 101.

[0078]A user can check a preview of an excluded object in an area 1305. In FIGS. 13 and 14, boxed portions define excluded objects. The user can select an object shown in the area 1305 as an excluded object through the UI unit 206. The user can also register the selected object as an excluded object by pressing a button 1301. That is, the user can select and register an object in an area in the image data as an excluded object.

[0079]The user can register a character object as an excluded object by pressing a button 1303. The user can al...

Abstract

An image processing apparatus and an image processing method are provided for allowing a user to achieve a desired image quality while controlling toner consumptions. An amount of toner reduced is calculated based on a set toner reduction rate. For objects other than an object specified as an excluded object to which toner reduction is not applied, a toner reduction rate for achieving the calculated amount of toner saved is calculated.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image processing apparatus and an image processing method for digitally generating and controlling image data for forming an image on a sheet, and a program for executing image processing.[0003]2. Description of the Related Art[0004]In an image forming apparatus, a processing mode for reducing color material consumption, a so-called toner save mode, is widely known as a function that lowers print density and reduces printing costs. In recent years, even for the processing in the toner save mode, an image quality equal to that available in ordinary printing is required while reducing printing costs.[0005]One such processing method is to retain a plurality of tables for toner saving used in printing so that an image having a quality equal to that available in ordinary printing can be obtained even by the processing in the toner save mode (see, for example, Japanese Patent Laid-Open No. ...
